These C4 string and washer envelopes are made from 180 gsm Kraft Paper. C4 String & Washer envelopes are a very traditional method of fastening an envelope and are ideal for handling sensitive documents or for use in internal mailing systems.
Manufacturing tolerances are given as +/- 2mm in any direction. The speed at which envelope manufacturing machines work together with the vagaries of the raw paper itself can lead to inconsistencies.
